Windows 7: Laptop internet turns off when lid closed

I have an hp laptop windows 7 64-bit, fully updated via windows update. I sometimes hook my laptop up to my TV via HDMI cable. (I am connecting to the internet and network via wireless card) I have it set in power options so that when the lid is closed "do nothing", unfortunately when the lid closes the internet doesn't respond and says there is a problem with the DNS server when there isn't any problem at all because all of the other devices on the network are working completely fine. Also the internet people ran a diagnostic and it's perfectly fine at almost 6 megs down.

I figured there was a problem with it when I close the lid the internet stops responding as for when the lid is opened the internet is fine. I went into the device manager and went to the properties of my wireless networking card and in there to power management and unchecked allow computer to turn off to save power or something like that. Anyways I'm at a lost I'm not sure what else to do. It seems the computer is still connected to the network just not the internet. I would like to be able to close the lid and internet browse on my tv if possible.

I will try that, but I think I found another solutions anyways. My F4 key changes the display from computer, duplicate, projection only or extended. So I just leave the screen open and do projection only and it turns off the laptop screen.
